Sometimes, the sheer scale of the universe amazes me. It's incredible to think that all our thoughts, all our experiences, literally every single thing that we've ever seen or heard, all took place in a tiny insignificant dot in our galaxy, which in turn is a tiny insignificant dot in the universe. In fact, we can also scale down and see how we are made up of tiny cells in our body, which in turn are made up of molecules and atoms[1]. Many artists, philosophers and great minds have often looked up at the stars for inspiration. As Plato says, "Astronomy compels the soul to look upward"[2]. And this leads us to consider philosophical questions like our purpose in the universe, and the amazing possibilities that could exist out there.
Humans are a naturally curious species, and so it only seemed right that space exploration came about. Since the mid twentieth century, humans have been trying to get further and further out into space to explore. So far, the only successful manned missions to a celestial body have been to our own moon, but we don't seem to be far from trying to get a manned mission to Mars[3]. One of the most interesting concepts currently is SpaceX, a company that's trying to privatize space travel, so any one with sufficient wealth can do it[4]. SpaceX's future goals include setting up a colony on Mars and making humans an multi-planetary species.

Space is one of the most fascinating subjects as it manages to stimulate people from both cultures[5]. It makes scientists and engineers think of the complicated astrophysics and quantum mechanics needed to explore it, while it makes artists and literary minds consider the philosophy of human life, its purpose,the possibility of extra-terrestrial life, etc. Space has been a prime subject for many novels, movies and plays simply because we don't yet know enough about it to know everything that's out there. It's great to see how rapidly we're building technology capable of taking us further out into the universe, and I'm excited to see what we discover out there.
